i did a worst death thread earlier for naruto, this time its, whats the worst/most gruesome death you've ever seen in ANY anime,, to kick it off i'd have to say ninja scroll where the stone skin guy got the spinning blade to the face and then slid right down,, i'm sure somebody will top that
Berserk has some very, very gruesome deaths. Particularly near the very end of Golden Age there is some really dark stuff, but in general Berserk was always a pretty darn brutal series.
Another one worth noting is the deaths in Higurashi no Naku Koro ni. Personally I find it even more disturbing than Berserk because while Berserk is the obvious fantasy setting deal, Higurashi is a much more down-to-earth series with deaths that, given a person goes through the exact same psychological turmoil as these characters, could very well take place in our world. Particularly in Meakashi-hen, the deaths of
Rika and Satoko
were really quite gruesome and I would post them but it's something some people (and I myself with this post being at like midnight) probably wouldn't wanna see.
